Application August 20,

6 Claims.

, The objects of this application are:

First, to provide a cord or edge roll for'finishing the edges of parts of furniture in which the soft core is a soft resilient fibrous substance and in which there is a reinforcing edge that may be cheaply and easily made.

Second, to provide such a cord with a reinforcing portion through which stitches or nails lmay be inserted Without tearing the cord.

Third, to provide an edge roll with attaching web that can be cheaply and leasily assembled and will withstand the attaching because of properly placed reinforcing.

Other objects and advantages of my invention will appear from the description to follow. Preferred embodiments of my invention are illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of a bat `of jute or other suitable material for use in making such a cord.

Fig. 2 is a perspective view of a section of the cord with the end portion of the material released from the braided covering threads.

Fig. 3 is a side elevation of such a cord.

Fig. 4 is a perspective View in section of an edge roll in the process of manufacture before stitching.

Fig. 5 is a perspective view of the finished edge roll.

Fig. 6 is a view of the cord shown in Fig. 3, attached to the furniture by means of nails.

rIhe parts will be identified by their numerals of reference which are the same in all the views.

l is a bat of jute fibres or other fibres suitable for manufacturing my improved cord. I have found that jute is successful because it possesses the necessary qualities of softness and resiliency. It is possible' to use hair that has been garnetted and made into bats or cotton or any similar material. The bat is cut into strips 2 which are rolled or folded as is shown in Fig. 2 or may be run directly to the forming die. The strip 2 is then passed through a forming die where it is compressed to a substantially cylindrical form. If desired, the forming die may impart different forms to the cord so as to form an attaching web thereon or to give oval or other form to the cord. The-cylindrica1 form, however, has special advantages. 3 is a strip of burlap or other fabric used to reinforce the cord. The strip partially covers the fibrous material and is shown here of a width suiiicient to receive stitches as in Fig. 5 or nails as in Fig. 6 to attach the cord to the furniture.

The strip 3 is arranged longitudinally of the 1932, Serial N0. 629,699

cord by placing the strip 3 on the strip 2 as it goes into the forming die. A guide is used to prevent spiraling of the strip, and it is pressed against the fibrous material as the cord is formed. The cord passes from the forming die to a braiding machine where it is covered with f ht threagsiwhich retain the fibrous material in t dsired shape and also retain the strip in position on the finished cord.

. It will thus be seen that the cord thus produced is much stronger than the cord without such a reinforcing strip and nails or stitches will not tear out as easily as they would if the fibrous material and the cords were depended upon entirely. The cord may be very cheaply' made without any additional labor and the burlap strip adds little to the cost.

Instead of jute or hair or other fibrous material, it is possible to use wadded crepe sheets of cellulose as is fully described in my Patent 1,821,582, issued Sept. 1, 1931, for Packing cord. If desired, an attaching web may be formed on the cord to make a pre-formed edge roll by running a row of stitches l1 longitudinally of the cord and through the reinforcing strip 3 as is shown in Fig. 6. The cord can be fed to a sewing machine through a proper die to form the web and the stitching pinches the material to retain the formed web.

In making edge rolls with attaching webs, two cords 5 and 6 constructed as above described may be used to good advantage because the reinforcing strip 3 makes it possible to stitch the cords together so that the smaller cord 5 will become an effective attaching web and will not be easily separated from the larger cord 6.

In manufacturing such an edge roll, the cords 5 and 6 are disposed longitudinally together with their reinforcing strips 3 and '7 in contact. The cords are then compressed in a forming die and delivered to a sewing machine. The forming die compresses the larger cord 6 and the smaller cords together as shown in Fig. 5 and a row of stitches 8 may be run so as to pass through both cords and their reinforcing strips. A second row of stitches 9 may be run down the smaller cord 5 to compress it to form the attaching web 10.

In Fig. 5, I have shown the reinforcing strips '1 of the cord 5 of such size that the row of stitches 9 passes through the reinforcing strip to make a stronger structure.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A cord or edge roll made up Vof matted fibrous material compressed to form, a fabric reinforcing strip disposed longitudinally of and covering a portion only of said material and braided wrapping threads embracing said material and said strip, whereby the material is retained and the strip is retained on the material.

2. A cord or edge roll made un of fibrous material compressed to form, a fabric reinforcing strip disposed longitudinally of and covering a portion only of said material and braided wrapping threads embracing said material and said strip, whereby the material is retained and the strip is retained on the material.

3. A cord or edge roll comprising a pair of cords lof different size arranged longitudinally together, each cord made up of batting of resilient fibrous material rolled and compressed to substantially cylindrical form having a fabric reinforcing strip disposed longitudinally of and partially covering said batting having braided wrapping threads retaining said batting and said strip, a row of stitches through the larger cord and its reinforcing strip adjacent its contact with the smaller cord, and through said smaller cord and its reinforcing strip, and a substantially parallel row of stitches through said smaller cord and its reinforcing strip, whereby said smaller cord is compressed to form an attaching rib.

4. A cord or edge roll comprising a pair of cords of different size arranged longitudinally 5. A cord or edge roll comprising a pair of Y' cords of different size arranged longitudinally together, each cord made up of matted fibrous material compressed to form having a fabric reinforcing strip disposed longitudinally of said material having braided wrapping threads retaining said material and said strip, and a row of stitches through the larger cord and its reinforcing strip adjacent its contact with the smaller cord and through said smaller cord and its reinforcing strip.

6. A cord or edge roll comprising a pair of cords of different size arranged longitudinally together, each cord made up of resilient material compressed to form having a fabric rein forcing strip disposed longitudinally of said material having braided wrapping threads retaining said material and said strip, and a row of stitches through the larger cord and its reinforcing strip adjacent its contact with the smaller cord and through said smaller cord and its reinforcing strip.
